Excerpt from Wikipedia, which is not the best source for game-changing critical voices towards the establishment *understatement* but 9/11 Press for Truth truly is a classic among the 9/11 documentaries.
9/11: Press for Truth follows three of the Jersey Girls (widows of individuals killed in the attacks) as well as other family members in their search for answers about what really happened on 9/11.
Among their questions were: Why had NORAD failed to protect the known terrorist targets, the World Trade Center and the Pentagon? Why did the World Trade Center Towers, including Building 7, completely collapse when no other steel-framed skyscraper had ever previously totally collapsed due to fire? Why did George W Bush stay in a Florida classroom for over 10 minutes after he had been told that the second Tower had been hit?
The film uses archive news footage, press conferences and newspaper clippings to document the unwillingness of the George W. Bush administration to provide answers to the families' questions or support a full independent investigation. It also shows how the mainstream media avoided asking the politicians the toughest questions.
